This doesn't parse well, so I venture to guess that Nicolas wouldn't 
like that.

See perhaps http://permalink.gmane.org/gmane.emacs.orgmode/68027 
(unanswered so far and was actually meant to solve a different cosmetic

See (1).

The comments would still be part of the arguments, so a special form of 
trimming would be needed.

Line continuation markers are only really useful with line-by-line 
evaluation or if the whole buffer gets preprocessed, so they are not a 
good solution for Org, IMHO.
